Every survey statistician knows the calibration method developed by Jean-Claude Deville and Carl-Eric Särndal. Unfortunately, Jean-Claude Deville passed away in November 2021. He was one of the most important survey statisticians of our time. This webinar is dedicated to his memory. First, we remind the most important contributions of Jean-Claude to survey statistics. Next, we focus on two of his contributions: calibration and cube method (balanced sampling). We show some very recent developments related to: 1) calibration with high-dimensional auxiliary data sets and 2) statistical matching of survey data trough calibration, optimal transport and balanced sampling.
